Word文書の選択にswitch文を使用する

Question

私は現在、ユーザの選択に応じてワード文書をマージするプログラムを持っています。現在、このプログラムは、図示のように5つのファイルの合計は、ボタンを押し経由でマージするために選択することができます：

// combine files in folder selected using MsWord.cs, 
    private void combineButton2_Click(object sender, EventArgs e) 
    { 
     loadingForm.Show(); // displays 'loading' form 

     // 5 documents selected by the user 
     selectedDocs = new [] 
      { 
      selectedFile1, 
      selectedFile2, 
      selectedFile3, 
      selectedFile4, 
      selectedFile5 
      }; 

     string fileDate = DateTime.Now.ToString("dd-MM-yy"); 
     string fileTime = DateTime.Now.ToString("HH.mm.ss"); 
     // output folder user selects    
     string outcomeFolder2 = outputFolder2; 

     string outputFile2 = "Combined Files " + fileDate + " @ " + fileTime + ".docx"; 
     string outputFileName2 = Path.Combine(outcomeFolder2, outputFile2); 

     MsWord.Merge(selectedDocs, outputFileName2, true); 
     loadingForm.Hide(); // to hide the form 

     // Message displaying how many files are combined. 
     MessageBox.Show("A total of " + selectedDocs.Length.ToString() + " documents have been merged", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information); 
    } 

現在の問題があり、ユーザーMUSTは5つのドキュメントを選択。彼らが2/3/4ファイルを選択すると、プログラムのエラーが発生し、全体の使用が制限されます。私はSwitchのステートメントを読んでいましたが、状況を改善するのに役立つかもしれませんが、私はコマンドに精通していません。それは、常に正確な右のサイズであるので、あなたは代わりにList<string>を使用して、最後の瞬間に配列に変換することができ

switch (merge) 
    { 
     case 'selectedFile1': 
      selectedDocs = new [selectedFile1] 
      break; 
     case 'selectedFile2': 
      selectedDocs = new [selectedFile1, selectedFile2] 
      break; 
     case 'selectedFile3': 
      selectedDocs = new [selectedFile1, selectedFile2, selectedFile3] 
      break; 
     case 'selectedFile4': 
      selectedDocs = new [selectedFile1, selectedFile2, selectedFile3, selectedFile4] 
      break; 
     case 'selectedFile5': 
      selectedDocs = new [selectedFile1, selectedFile2, selectedFile3, selectedFile4, selectedFile5]     
      break; 

      default: 
     MessageBox.Show("error, no files selected"); 
      break; 
    }

Answer 1

：私はそれが何かを行くと仮定します。

List<string> doclist = new List<string>(); 
doclist.Add(selectedFile1); 
//...etc. 

//Then... 
MsWord.Merge(doclist.ToArray(), outputFileName2, true);
